I have a piece of code (my app) which I want to run for each incoming call in the iphone.
So I'm looking for a function like: On Before Incoming Call ();
is there anything like that?
I have a class with a number of fields which are normally calculated in the constructor from other data in the class. They are not serialized to XML because any changes to the rest of the data will likely require their recalculation.
Is there a way I can set up a function call to be triggered on deserialization?
Here are the GDI functions Chord() provided by MFC:
BOOL Chord( int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4 );
BOOL Chord( LPCRECT lpRect, POINT ptStart, POINT ptEnd );
It seems to me that no such method is privided by GDI+ (the Graphics class), so how do I implement my own Chord function (with the exact same prototype) ?
By the way, I just don't understand why does MS just don't provide them.
Thanks.
function sk=skeleton_finding(x)
% calculate distance transform
dt=bwdist(~x,'cityblock');
% find the local maximum
n=[0 1;-1 0;0 -1;1 0];
sk=dt>0;
for i=1:4
sk=sk&(dt>=circshift(dt,n(i,:)));
end
Can someone illustrate?

I have a page that has a tab set. Each of the tabs is loaded by the jQuery .load() function.
I want to display a loading animation that disappears when all of the ajax requests are finished. However, document.ready() has only provided me with limited success.
How can I ensure that all ajax requests are completed before executing the code to hide the loading animation?
Thanks!
I'm looking for something similar in form to weighted.mean(). Sorry for posting such a banal question... new to R. I've found some solutions via search that write out the entire function but would appreciate something a bit more user friendly.
I have been trying to get this array function to output (non-zero) minimum values in the 'FINAL DATA' AE column. Can you see a structural error in this formula?
=IF($C$4="All EMEA",
MIN(IF('FINAL DATA'!$2:$AE$250000<>0,
('FINAL DATA'!$J$2:$J$250000=$C$4)*('FINAL DATA'!$E$2:$E$250000=$E$4)*( 'FINAL DATA'!$AE$2:$AE$250000))),
MIN(IF('FINAL DATA'!$AE$2:$AE$250000<>0,
('FINAL DATA'!$K$2:$K$250000=$C$4)*('FINAL DATA'!$E$2:$E$250000=$E$4)*( 'FINAL DATA'!$AE$2:$AE$250000)))
)

Hi guys.
I read about function pointers in C
And everyone said that will make my program run slow.
Is it true?
I made a program to check it.
And I got the same results on both cases. (mesure the time.)
So, is it bad to use fuction pointer?
Thanks in advance.
In NHibernate there is a merge function that does the following:
if there is a persistent instance with the same identifier currently associated with the session, copy the state of the given object onto the persistent instance
if there is no persistent instance currently associated with the session, try to load it from the database, or create a new persistent instance
the persistent instance is returned
Is this possible in EF? I mean this part : copy the state of the given object onto the persistent instance. And if i used ApplyCurrentValues it seemes to be as update behavior or not?
class a
{
virtual void foo(void) ;
};
class b : public a
{
public:
virtual void foo(void)
{
cout<< "class b";
}
};
int main ( )
{
class a *b_ptr = new b ;
b_ptr-foo();
}
please guide me why the b_ptr-foo() will not call the foo() function of the class b?
Hi!
Im trying to do a simple fadeIn ONCE for the first div , but the problem is that this is a ajax load inside a everyTime(xxx sec), so it does the same thing everytime it loads again.
anyone got any ideas on how i can prevent the first div to fadeIn over and over again, but still do this function on the new div?
Not very familiar with Jquery.. so feed me with a spoon :)
I recently learned that all stl containers have swap function:
i.e.
c1.swap(c2);
will lead to object underlying c1 being assigned to c2 and vice versa.
I asked my professor if same is true in case of c1 and c2 being references.
he said same mechanism is followed.
I wonder how it happens since c++ references cannot be reseted.
This is too basic I think, but how do both of these work?
return true; // 1
and
return (true); // 2
Similar: sizeof, exit
My guess:
If return was a function, 1 would be
erroneous.
So, return should be a unary
operator that can also take in
brackets... pretty much like unary
minus: -5 and -(5), both are
okay.
Is that what it is - a unary operator?
Hi there,
I tried to pass a string value into a JavaScript function like below:
<%= "'" + prop.property_description + "'") %>)
But it does not seems to be the best option, is there a better way to do the above without concatenate the string values with "'"?
Thanks
Hi everyone:
I have a question, here are two class below:
class Base{
public:
virtual void toString(); // generic implementation
}
class Derive : public Base{
public:
( virtual ) void toString(); // specific implementation
}
The question is:
If I wanna subclass of class Derive perform polymophism using a pointer of type Base, is keyword virtual in the bracket necessary?
If the answer is no, what's the difference between member function toString of class Derive with and without virtual?
Class Test{
int value;
static void* thread_func(void* args){
value++;
}
void newthread(){
pthread_create(&thread_func,...);
}
}
I'm trying to create a thread in Class Test. Therefore compiler forces me to make thread_func static. However I cannot access the non-static member "value" anymore. It says:
invalid use of member 'Class::value' in static member function
Is there a way around it?
I am using the function CertCreateSelfSignCertificate (http://msdn.microsoft.com/en-us/library/aa376039(VS.85).aspx) to generate a certificate. I need to specify the key size to be 2048. I do not see how to provide this parameter.
I would appreciate any help in this matter.
Thanks.

Is there a way to have keyup, keypress, blur, and change events call the same function in one line or do I have to do them separately?
The problem I have is that I need to validate some data with a db lookup and would like to make sure that there is no way that the validation is missed weather it is typed or pasted into the box.
How can I set a conditional breakpoint to a function's 3rd line in GDB?
I know I could give the file name + line number but this is not working for me.
I have to store the gdb commands as a script to repeat it later and I don't want to change the script every time the source file is changing.
I create empty project. Add some dll and lib. Then I include header file from one library and the program begin ignore main function, when i execute it.
No errors during building was.
Such behavior shoke me. It seems program use DllMain or so on.
Any suggestion?
Thanks.
